Update to DRO+ website

Whew! I just got done updating the website. Lots of visual
changes, including a full rewrite of the site. Hope you like the
new layout. Take a look at http://www.mcs.net/~kulaga/dro.html
and let me know what you think.

I also posted the newest version of the software. It includes:

- Metric/english units
- Autodetect and support for 4 axis boards (4th axis in degrees)
- Backlash compensation! Finally!

For those of you who bought the etched board that Dan Mauch was
selling, he sent them out, so you should have them soon. I got
mine, and boy, it's nice. He also included a good set of
instructions with it. You'll need the latest software to use his
board, so go get it. If there's anyone out there who didn't get
a board but would still like one, he's got a few extras as of the
last time I talked with him. Email him and ask. His contact info
is on my website.

Now that the site is done, I'm going back to messing with the
software. Any suggestions are gratefully accepted. The backlash
compensation has not been fully tested, so those of you who use
rotary encoders, try it out and give me feedback. I haven't
written a good tutorial on how to measure and set it up, so email
me and we'll hash things out.

Thanks to all of you who have given feedback, support, or help.
It really keeps me going, especially when the hobby stuff gets
buried under real life.
